31. Sita is younger than Bimi by 7 years and their ages are in the respective ratio of 7: 9, how old is sita?
A. 25
B. 24.5
C. 24
D. 23.5
Answer
Explanation:
Let the ages of Sita and Bimi are 7x and 9x respectively
7x = 9x-7
x = 7/2 = 3.5
Sita's age = 7x = 7 × 3.5 = 24.5
32. A is as much younger than B as he is older than C.If the sum of the ages of B and C is 50 years, what is definitely the difference between B and A's age?
A. Data inadequate
B. 3 years
C. 2 years
D. 5 years
Answer
Explanation:
Age of C < Age of A < Age of B
Given that sum of the ages of B and C is 50 years.
Let's take B's age = x and C's age = 50-x
Now we need to find out B's age – A's age. But we cannot find out this with the given data.
33. The total age of A and B is 12 years more than the total age of B and C. C is how many years younger than A?
A. 12
B. 24
C. C is elder than A
D. None of these
Answer
Explanation:
(A+B)-(B+C)=12
A-C=12
34. Sujina's father was 38 years of age when she was born while her mother was 36 years old when her brother four years younger to her was born. What is the difference between the ages of her parents?
A. 6 years
B. 5 years
C. 4 years
D. 3 years
Answer
Explanation:
Let Sujina's age = x and her brother's age = x-4
Sujina's father's age = x + 38
Sujina's mother's age = (x – 4) + 36
Sujina's father's age – Sujina's mother's age
= (x + 38) – [(x – 4) + 36]
= x + 38 – x + 4 – 36
= 6
35. In a group of 4 friends, P is the eldest and R is the youngest. Neither is of the same age as the others. The sum of the ages of R and S is greater than twice the age of Q. Who is the second eldest?
A. P
B. Q
C. R
D. S
Answer
Explanation:
Let,
Age of p as P
Age of R as R
Age of S as S
Age of Q as Q
Now, according to question,
R+S>2Q
Q<R+S/2
Since R<Q, S>Q
So, R<Q<S<P
So R is the second eldest
36. If 6 years are subtracted from the present age of Anil and the remainder is divided by 18, then the present age of Roman is obtained.If Roman is 2 years younger to Dipendra whose age is 5 years, then what is Anil's present age?
A. 50 years
B. 60 years
C. 55 years
D. 62 years
Answer
Explanation:
Present age of Dipendra = 5 years
Present age of Roman = 5 – 2 = 3
Let the present age of Anil = x
Then (x−6)÷18 = present age of Roman = 3
x – 6 = 3×18
x – 6= 54
x = 54 + 6= 60
